Packing and voids in electro-rheological structures of polarized clay particles
K. P. S. Parmar, Y. Meheust, J. O. Fossum +2
Oil suspensions of fluorohectorite clay particles exhibit a dramatic meso-structural ordering when submitted to a strong electric field. This is due to dipolar interaction between…
Electrorheological suspensions of laponite in oil: rheometry studies under steady shear
K. P. S. Parmar, Y. Meheust, J. O. Fossum
We have studied the effect of an external DC electric field (~kV/mm) on the rheological properties of colloidal suspensions consisting of aggregates of laponite particles in a sili…
Using synchrotron X-ray scattering to study the diffusion of water in a weakly-hydrated clay sample
Y. Meheust, B. Sandnes, G. Lovoll +6
We study the diffusion of water in weakly-hydrated samples of the smectite clay Na-fluorohectorite. The quasi one-dimensional samples are dry compounds of nano-layered particles co…
Intercalation-enhanced electric polarization and chain formation of nano-layered particles
J. O. Fossum, Y. Meheust, K. P. S. Parmar +3
Microscopy observations show that suspensions of synthetic and natural nano-layered smectite clay particles submitted to a strong external electric field undergo a fast and extende…
